Why don't we just block off the exhaust pipe to prevent CO2

Click For Summary

Discussion Overview

The discussion revolves around the idea of blocking off exhaust pipes to reduce carbon dioxide emissions, with participants exploring the implications of such an action and comparing it to human respiration rates during activities like jogging.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants propose that capping an exhaust pipe would reduce emissions and address climate concerns.
  • Another participant humorously suggests that holding one's breath could achieve similar results.
  • A participant provides a calculation comparing CO2 emissions from cars to those from human respiration while jogging, concluding that the emissions are roughly equivalent.
  • There is a suggestion that if jogging produces similar CO2 emissions as cars, then jogging should be banned.
  • A later reply dismisses the discussion as nonsense and indicates a desire to end the thread.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are competing views on the validity and seriousness of the initial proposal and the subsequent calculations.

Contextual Notes

The discussion includes speculative comparisons between vehicle emissions and human respiration, with calculations that may depend on various assumptions about activity levels and physiological factors.

If you were to put a cap on your exhaust pipe your emissions will reduce thus you would solve the whole paranoia of climate shenanigans.

You could accomplish the same by holding your breath for a realllly long time.

When purchasing a new car these days we are informed that it pumps out 150g of carbon dioxide per mile travelled.

The vital capacity of adult male lungs is about 4.6 litres.

Say 40 breaths per every minute while jogging give total "exhaust" 184 litres per minute.
I doubt vital capacity could be maintained for a mile so let's call this 150 litres per minute.5% of this 150 litres per minute exhalation is CO2, i.e. 7.5 liters of CO2 per minute while jogging.

Jogging speed is approximately 6 miles per hour, (a mile in 10 minutes), => 75 litres of CO2 per mile.

That's about 3.3 moles of CO2 which is 147 grams.

So the CO2 emission of an adult male jogger is approximately 150 grams per mile.Carbon Dioxide Emission per Person (m3/h) cu metres/hour

Sleep 0.013

Resting or low activity work 0.02

Normal work 0.08 - 0.13

Hard work 0.33 - 0.38

Ergo - let us ban Jogging

This is nonsense. Thread locked.
